Discover world-changing science. This data-driven activity accompanies the video Selection for Tuskless Elephants. This video follows ecologist Caitlin O'Connell-Rodwell, who is studying how elephants can communicate over long distances using low-frequency sounds that travel both in the air and through the ground. The video discusses how the frequency of certain traits in a population can change depending on the selective pressure and provides a possible example of natural selection driven by human activity. Typically, though, such studies focus on small creatures that have large population sizes and fast generational turnovers because changes they undergo are easier to observe in real time. It engages students in analyzing data to make evidence-based claims about the occurrence of tusklessness in elephant populations. Students apply what they have learned to evaluate the results of different tests that have been used throughout sports history to qualify female athletes to compete.

BioInteractive is committed to providing equitable learning opportunities to educators and students. Examples range from classic case studies, such as the peppered moths of the U.K. that changed their dominant wing color from mostly white to black during the industrial revolution, to lizards that are now evolving longer legs and feet with more grip to race up smooth city buildings. Most African elephants have tusks, but some never grow them especially in places that have a history of poaching, like Gorongosa National Park. In this video, Poole explains a possible reason.

Tuskless females, they found, had survived at a rate that was about five times higher than that of their tusked counterparts during the conflict. HHMI is investing in increasing racial, ethnic, and gender diversity in academic science to create environments in which everyone can thrive. This study is among the first to show that selective killing of large vertebrates can have a direct impact on evolutionary change, says Fanie Pelletier, an ecologist at the University of Sherbrooke in Quebec, who co-authored a perspective piece in Science about the research. 6. endstream endobj startxref Tusklessness, according to a new paper in Science, can be attributed in large part to a dominant mutation on the X chromosomea genetic change that also explains the sex skew Poole saw.

For context, this course consisted of a three-credit lecture and a one-credit lab. Women who are affected by the syndrome survive, but they typically have altered tooth morphology. Poole, who is a co-author on the new paper, combed through old natural history films and amateur videos to estimate the prevalence of tusklessness prior to the war. Fortunately, another research team was carrying out a collaring project to track matriarch elephants. Resume watching the video until Like other places that had undergone intense poaching, Gorongosas female elephants exhibited an abnormally high proportion of tusklessness. In this activity, students engage in key science practices that scientists used to figure out ecosystem dynamics in the Serengeti.

Using those samples, they identified candidate regions in the genome that, when mutated, seemed to explain tusklessness and its apparent male lethality. In Gorongosa National Park, Poole found that among the older female elephants, who survived a period of heavy poaching in the park, over 50% are tuskless. Most of the elephants killed naturally did have tusks. This activity explores images of elephants with and without tusks, which serve as phenomena for learning about selection and human impacts on the frequency of traits within populations. Poaching brings evolutionary pressure for tusklessness. 2. Some prevent pathogens from entering the body, and some attack pathogens already inside the body.

One of the genes, AMELX, is known from decades of basic research in mice and humans to play a role in mammalian tooth development. In Gorongosa National Park, Poole found that among the older female elephants that survived a period of heavy poaching in the park, over 50% are tuskless. Poachers, she knew, prioritized elephants with the largest tusks. Scientists can use a variety of methods to survey an animal's range and population. What did Dr. Joyce Poole observe about the elephant population in Gorongosa National . Explore the methods scientists use to survey elephants. 2 Poaching is selecting for tuskless elephants, which are more likely to survive, mate, and pass on their genes. But in males with no other X chromosome to fall back on, that mutation appears to cause death in the womb. There was a huge skew in the sex ratio, with very few adult males. 318 0 obj <>stream To determine the traits prevalence after the conflict ended, she used a database of individual elephants that she and her husband and research partner Petter Granlialso a co-author of the new studyhad already built to study elephant behavior and communication.

This video follows scientists working in Gorongosa National Park as they try to determine the genes responsible for tusk development in elephants. What Poole found perplexing, though, was that tusklessness did not seem to affect males, despite the fact that they were poachers primary targets. It engages students in analyzing data to make evidence-based claims about the occurrence of tusklessness in elephant populations. Elephant tusks are important for obtaining food and water, and essential to male elephants for competing for mates, so one might expect strong natural selection for having tusks. As of 2014, about 350,000 savanna elephants were living in Africa. This interactive video explores how scientists identify which bat populations are infected with Nipah virus and could transmit the virus to humans.
